DOS GALGOS HOUSE









From the beginning, the beneficiaries came up with a very clear theme, which later drew the design line for both the exterior and the interior, namely a design inspired by the traditional farmhouse.  A combination of the atmosphere of the English farmhouse was desired, but with the spatiality and minimalism of American lofts.

Starting from here, but also from the constraints of the land with an L-shaped footprint and eccentric access on one of the short sides, the house was placed naturally on this footprint, copying the shape of the land, with the functions gradually unfolding, public-semi-private-private, from the access to the land towards the back of the lot.

The reception spaces, public - kitchen, living room, workshop and the private ones - the bedrooms - are grouped in two distinct bodies joined on the inside by a completely glazed passage, and on the outside, by a perimeter awning that defines and amplifies the horizontal silhouette of the house.




The canopy widens and narrows depending on the orientation towards the cardinal points and the subordinate spaces, transforming into a large console in front of the main terrace, to the west and almost disappearing on the north side, in front of the bedrooms.











This strong horizontal line is counterbalanced by the vertical rhythm of the structural pillars, clad in natural stone. The vertical elements rhythmize the facade and the exterior space, subtly canceling the feeling of a "corridor".

At the exterior design level, the courtyard follows the same principles as the interior, namely a cascade of courtyards with an increasingly intimate character, depending on the space to which they correspond: the bedrooms and the two rooms dedicated to hobbies (workshop room and sports room) each benefit from direct opening onto a private courtyard/terrace, while the living room opens wide towards the main courtyard enriched with a swimming pool and a second living room, mirroring the interior one.







A special emphasis was placed not only on the materials used but also on their texture. The exterior is defined by only two main materials: black sheet metal and natural stone, with a broken appearance. Natural stone is also extended to the interior, where it is combined with natural wood. The apparent austerity resulting from the almost exclusive use of only three materials: sheet metal, wood, stone is compensated by a rich play of textures resulting from the processing of materials with different techniques.

The house is on a single level. The archetypal section of country houses, with the truss-type roof, is also taken up inside, contributing to the general atmosphere.

I HOUSE





Section Prize „Interior Residential Design ” Bucharest Architecture Annual 2025 Nomination „Individual Housing” Bucharest Architecture Annual 2025




The present work is a rehabilitation and an almost complete reconfiguration of an existing Florentine-Moorish style house — a style often found in interwar Bucharest in houses and apartment buildings known for a high quality of architectural expression. Its most frequent elements include calcio vecchio plaster, twisted spindle columns with floral capitals accompanying arches or windows, arched, broken, or flattened openings, consoles with buttresses, and prominent window sills.

The challenge of the project was to reintegrate the original architecture with its specific details and materials into a building that is completely reconfigured on the inside and partially on the outside — a modern structure in which technology and functionality support spatiality.

The process was long, beginning in 2019, and involved three building permits: two for the main body and one for the gazebo extension and walkway construction. The main volume was extended vertically, the arched windows lost their parapets, and the street-facing window was reconfigured to receive more morning light from the east.

The spatial reconfiguration was necessary to enable a functional reorganization and to bring scale and light into the interior. Through this, we created two major vertical spaces — the orangery and the dining room — which became the most representative living areas of the house, complemented by the living room and the exterior pavilion.





The interior design is limited to a few materials characteristic of the period in which the house was built — mainly mosaics, parquet, metal, stone, and decorative plasters — with areas of apparent sandblasted concrete. Externally, mosaic and washed mosaic finishes were used. The stamped lime plaster was restored on all façades and inside the orangery. 

The joinery was custom-designed for the location using steel profiles with thermal breaks. The furniture is custommade and uses walnut veneer, recomposed veneer, solid walnut wood, marble and marble mosaic. The terazzo poured over the underfloor heating followed two different recipes for the interior and for the exterior and greenhouse.

The brasserie on the ground floor of Stabilimentul Creativ La Mița Biciclista is the most open of the building's spaces, with large windows facing Biserica Amzei and Cristian Tell streets. Light fills the interior in abundance during the day, and in the evening the light of the space warms this corner of the historic district.






Setting up the brasserie was yet another foray into the protagonist's personality - an exercise of imagination that brings out the story with real biographical facts, traits of her known personality and some recomposed ones. If the upstairs bar was an invitation to Mița's exclusive boudoir, the Brasserie is an open door to the guest lounge. A salon in which, if preserved, we would probably have had an ornate ceiling, golden chandeliers, paneled walls and marble floors with floral inlays, velvet curtains, carved and upholstered furniture, silver and crystal ornaments. 



Maria Mihăescu became known after an article that recounts the victory of the flower beating contest in Paris on the Champs-Elysees, at the end of the 19th century, with her whip decorated with flowers - a fashionable event of the time that was also held in Bucharest, on the Kiseleff Blvd., annually on May 10th. 

This incident propelled Mița's career as a high class escort, back in Bucharest, where she impressed with her beauty, boldness, extravagance, non-conformity and affinity for luxury. 

The fitted velvet trousers, the bicycle with the silver handlebars, the short haircut, the blouse with puffed cuffs, the white bonnet and her beautiful face are just some of the images that have reached us, surrounding an extravagant, playful, self-assured person who loves the shine.





Today we imagined the Brasserie as a place open to the city where you can read part of the protagonist's personality and the brilliance of the beginning of the century.

DANUBE DELTA
RESORT






„The Delta? A fantastic peace. An infinite peace. A vast tract of water and reed...Vast and recomforting, inspiring a perfect tranquility and calm.„ - Louis de Fries
Status: Concept Study
Location: Danube Delta, România
Built area: 6663 sqm

In the embrace of the Danube Delta, Jurilovca resort emerges as a sanctuary, offering a unique experience where myriad bird and animal species converge in a wild tapestry of life. Ancient settlements bear witness to the intersection of diverse civilizations neighborhood.



Confronted with this exceptional setting, our architectural vision sought to envision a
tourist resort, navigating the delicate challenge of fostering development while preserving the delicate balance of natural life and the local community.


The design ethos embraces the responsibility of harmonizing growth with environmental
and cultural integrity, creating a haven that coexists seamlessly with the pristine
surroundings.







The Danube Delta Resort complex is composed mainly of existing buildings-the fish can factory, the Cherhana, the wood and the mechanic workshops, the weaving mill and sewage treatment plant-a mix of industrial sites within a traditional village setting. The complex is separated into two areas: the 4 star area and 5 star hut area.







The unique character of the Jurilovca area results from the fact that, within a relatively
small area, almost all major landscape types of Tulcea County are encountered. Traditional Lipovan houses, usually built by local craftsmen, are arranged along wide streets, developed according to a geometric layout. The façades are richly decorated and painted in shades of white, blue, green, ochre, and grey, with reed roofs and tympanums distinguishable by their intricate ornaments of fretworked wooden gables.

Informed by this rich heritage, several tourist accommodation archetypes were designed:





The 5 star “family huts”,  with footprints varying between 51 mp to 65 mp, can accommodate guests in up to two bedrooms per quaint unit. The 4 star area spans carefully restored heritage structures—the Carpentry Workshop, the Lathe Workshop, the Weaving Mill, the Smokehouse, and the Canning Factory—which merge original character with upscale hospitality standards.

The leisure sector includes various sports facilities such as a nautical club with a lounge pavillion and a luminous tea house that can accommodate up to 32 guests; these facilities serve the swimming pool and beach area and are designed to blend seamlessly into the endemic vegetation.


The Danube Delta Resort complex also features a generous fishermen’s hall (cherhana) and a restaurant with its own greenhouse, as well as the Jurilovca House, designed to host from boat workshops to cultural activities.











The proposed materials primarily reconnect the specific elements that give character to
the place; through them, the buildings seek to integrate both chromatically and texturally. Through the use of materials, a contemporary identity is created, connected to tradition and industrial heritage.































The main construction materials used in the area are adobe, clay, wood, and reed. With the development of transport along the Danube and the canals, stone also appears.

Earth, formerly the main construction material, was traditionally used for: filling walls built using the “lath” technique with clay; constructing the walls of houses and certain household annexes through the production of adobe blocks; daubing the reed or wattle walls of
houses; finishing walls made of adobe, wattle, or clay; creating the floor structure in combination with reed; plastering the porch; plastering the floors of the dwelling; constructing foundations; forming the upper layer of stone fences; building bread ovens or blind stoves, etc.


Stone, quarried from sites within Tulcea County since the end of the 19th century, was most often employed in the construction of foundations, plinths, and porches.

Wood: Fir, linden, willow, poplar, and more rarely dog-wood were used for wall construction, as forked posts, horizontal battens, laths, and poles. Fir wood was—and still is—used for roof structures, particularly for the main beam, with smaller beams made of twigs (today of laths). The ceiling of the house, the porch, and the gable are made of wooden boards. Decorative elements (“florăria”) were created through fretwork and then fixed to the fascia board or the gable. Doors and windows were also made of wood.

Reed was used both for constructing walls and roofing, as well as for enclosures. In the attic of the house, reed was laid over the cords, thus creating the support layer over which earth was applied in the form of clay.

Our intervention is composed of a main body with the role of a hotel, diagnostic, treatment, relaxation and recovery center and a series of pavilions placed on the level curves of the land with a rather large slope.



The architectural searches respect both the traditional heritage of the Gorju area which also inspired Brancusi in his works, the registers of traditional houses with stone plinths and dark brown wooden floors, the sloping roof, the woodwork and attention to the combination of wooden elements, the sincerity of the structure , as well as the natural context, by using natural materials (natural stone extracted from quarries in the area and brown wood obtained by traditional methods).




The main body opens to the river valley through a stone portico, a filter between inside and outside that pushes the limits of the spaces on the ground floor to the outside. A sustainable approach through the quality of architecture and materials, details and long-term thinking.

We offer you a quality space, with an interior anchored in nature and local culture.




Nowadays, luxury can mean different things, in our case it means primarily a healthy space and a definition of a way of life inspired by creativity and enthusiasm.



 


Respect for nature and sustainability forces us to use traditional materials and techniques, the production of which did not emit a large amount of carbon dioxide.

To use as many local materials and elements as possible, including to have the right to say that nature is integrated into the DNA of the project.






The interiors are inspired by the most distinctive color of southern Transylvania – blue – and they use natural and heat-treated wood to build a pleasant and naturally olfactory environment, both the wool carpet and the color of the light lead to a modest country interior in appearance, but rich in sensation and consistency.









The lobby area makes a more direct connection with the mountain through the predominant stone material and its textures, warmed by the natural lime and wood plasters.

And the SPA area takes the guest to an experience dug deeper into nature, where the fire that processes wood meets stone and water.

Hotel Făgăraș explores the limitations and possibilities of an existing building built in 1953-1954. Appeared as a result of the need for housing units for the technical staff of the Nitramonia complex in Făgăraș, the building is part of a small ensemble made according to typical projects specific to the period, significant for its unitary quality.








The conversion from residence to hotel involved subtle overall alterations, predominantly consisting of the release of the existing framework and its transformation from loft to attic, thus making the space suitable for temporary living. 

The added dormers in the attic replicate the gaps in the lower registers, remaining within the parameters of typical Stalinist academicism.






The access to the hotel below the level of the natural terrain creates the opportunity of a distance from the street and the living area, subtly separating the two worlds, that of the neighborhood and permanent housing, from that of the hotel and temporary housing.

The project aims to render the city building in its most convenient form, leaving the context unchanged through its transformation.

The starting point of the interior concept are these very characteristics: the mystery, sensuality and exclusivity that the interior of a boudoir once presented. We achieved these particularities through carefully choosing the precious materials, with different textures and transparencies, as well as light fixtures that create distinct lighting scenarios, addressing the need of the client to transform the atmosphere according to the current event.









In the floor plan, the bar is centrally placed, inspired by the geometry of a secretaire, with reinterpreted brass handles and a massive green marble top. The back bar frames this perspective through the shelving unit for the alcohol bottles. The shelving is commanding through size, but is dainty, thanks to the materiality of the perforated brass and its delicate process of manufacture. The space is remodeled through mirrors placed on the back bar, creating depth, while the suspended round mirror gives guests a view of themsleves in the boudoir atmosphere.

The toilets continue a story of feminine sensuality with an even deeper look beyond the boudoir.
